This: invention relates to the .art of ing, and is'. for a color "carriage ofthe type commonly used 'in block printin'grmachines, such for instance, asrthose used inthe decorating of linoleum andfelt base-floor covers.

1ngs.' r

In block printing machines the printing blocks are arrangedxtransversely of'the direction of travel of the strip'of-materialbe-r ing decorated. The blocks are moved down into contact with the material to be printed and then lifted, and while they 1 are eievated a paint fountain moves" across the surface thereof'to apply color to the printing. sur-v face; thereof] It has been proposed to .divide the paint fountainlongitudinally into a plu'ralityqof compartments whereby difier- Je'nt portions of theroll in the fountain will V appreciable width in Ordermto prevent the apply different colored paint to different dis visionsofthe printing-block;

- The partitions in the colorbox must be of color from one compartment working over into the-colorin the next compartment; By

' reason of this the portions of"the'block,loe

cated over the partitions do not receive color at all. This necessitatess-peci-ally adapting the pattern o'f the rug torthe division's in-the;

paint carriages sothatf the portions of the patterniwhichmust be left blank by one block are filled in by a, succeeding block, the partitions: of the carriages for successive blocks being staggered. I

With the present arrangement thereis provided a color boxso divided that the color divisionswill meet onl'the same-line and no 'spacecneeds-to be left-sbyreason of the par-,

1 titions in'the trough; The" invention can be adapted it use in machines wherein, the ordinary "printing blocks are employed, or it can beused with machines having the printing blocks divided into aplurality of sections transversely and/or longitudinallyrns suggested .forji'nstanceinthefapplication of Nil:

Jliam Penn Brinton, Serial No. 247,319, filed January 17,1928, The invention is also adapted for use' in anarrangement where vertical movement is efiected between the color carriage and the block" during the passage of the color carriageunder the block, as

disclosed in the application-of Robert A. Bgalderson serial No. 291,818 filed July 11th, 1 28. v i

The invention may be readily understood 7 by reference to the-accompanying drawings wherein V Flgure' 1 .1s a plan view of a color'carriage constructed in accordance With my invention the outline of the printing- :block being shown in broken lines;-and

modified color fountain.

Inthe drawings 2 designates abcolor carriage having a central partition 3 extend ing longitudinallythereof and dividing the carriage into-two compartments 4 and -5. In thecompartment i are transverse partitions 6U: Figure 2 is a similar view of a slightly 6 by means of which the compartment L is 7 divided into short sections, 4 4:", 4, and. 4

Similarly the compartment 5 is dividedby partitions 7 into relatively short sections 5?,v 5 ,c5,wand' 5 ..v The partitions 7 are stag-V gered with reference to the partitions 6. 'In

the particular embodiment shown, the com:

partmentfi is longer than the compartment projects beyond the end thereof,fthe projecting ends being provided with driving gears as is common in the art. 'The shaft 8 is partipacked where it passes through the tions, as is also known in the art.

In the compartments 5 and 5 are color applying rollers 9 and 9 respectively, these rollers being carried on the shaft 9 which is arranged similarlyto the shaft 8. The right hand end of the roller 9 and the left hand end of the roller 8 both extend to substantially the same line XX.' Similarly the right hand end of the rollers Stand the left, if

hand of the roller 9 end onthe line YY;.

The ends of the rollers 99 and 8? end onthe;

linfe Z-Z. s r

It will thus be s eenithat no long the compartments Retaand 5?, etc,

' to the same line.

V and cl, it being possible to apply the color up to the line of juncture. It is not necessary that a space equal to the'width of the partitions 6 or 7 exist, is necessary with the present practice, where the color carriage contains but a single trough.

. The construction shown in Figure 2 is sub stantially the same as that shown in Figure l, and the same reference numerals have been used with a prime afiixed thereto to. desig nate the corresponding parts. In this arrangement, however, all of the divisions in the compartments A and 5. have a color roller. This arrangement can be used in the same Way that the arrangement. shown in Figure I is used by merely leaving-some of the coinpartments empty so that the rolls do not apply paint. This arrangement can also be used with a divided printing block such as shown inthe Brinton application or can be used where vertical movement is effected be-.

, tween theblock and the carriage during the passage of the carriage under the block as said. troughs having transverse partitions therein.

2-. A color carriage having a plurality of longitudinally extending troughs divided transversely into. compartments, the parti-.

tions betweenthe compartments being. stage gered,

3. A longitudinallyextending compartments with transverse partitions therein, the partitions A in the compartments belngstaggered, and

paint applying rollers in some of the compartments.

a. A color carriage having two series of paint holding compartments, one arranged in advance ofthe other, the ends of thecompartments of one seriesbeingstaggered with respect to the ends of the'coinpa'rtments ot the other series, and paint rollers! in the con ipartmentsflhe ends of the rollers-in one series.- of compartmentsterminating insubcolor carriage having at least two.

stantially the same plane as the opposite ends of the rollers in the other series ofco npartments.

5. A color carriage having two series of parallel compartments, the compartments of one series overlappingthe compartments of the other, and paint applying rollers in some at least of the compartments of each series,

the rollersin thecompartments of the two series terminatingin substantially the same transverse plane. 1

6, The combination With a printing block, of a color carriage for applying different colors to closely adjacent areas of the block,

said carriage having two longitudinally extending compartments, a color applying roll in each compartment, the rolls being of less length than the compartments, the right hand end of one roll being in substantially the same plane as thelett hand end 0f the other roll.

7'. A color carriage having a pair of; longitudinally extendingcompartments, color applying roll sections in each compartment staggered with reference to each other, some of the roll sections in one compartmentterminating in substantially the sa'metransverse plane as the opposite ends. of the roll sections in the other compartment.

8. A color carriage having a pair of, longi: tudinally extending compartments, color applying roll sections in each compartment staggered with reference. to. each other, some of the roll sectionsin one compartment terminating in substantially the same transverse plane as the oppositeends of the; 120.1 B iQI in the other compartment,.and transverse partitions at the ends of thesaid L'Oll sectio s.

9. The combination with a printing block of a block printing machine, of a longir tudinally divided color boxhaving parallel troughs, a roll section in one: trough, a, roll section in theother trough, the lefth-and. end of oneroll section being: in substantially the same plane as therighthand end of the-other roll section.

10. A color carriage. for use in a. block printing machine comprising a trough-like body having a single partition extending down the middle thereof, which partition divides: the body intotwo longitudinally ex: tending troughs, and transverse partitionsin said troughs, the: transverse partitions beingin staggered arrangement, and paint-applying rollers lying" in compartments of saidv 1;

troughs formed by the transverse partitions. In testimonywhereof'il have hereunto set.
